What is health research?
health research is Research on all aspects of health, the factors affecting it, and ways of promoting, protecting and improving it. It is an essential part of national health development. It includes medical and biomedical research relating to a wide variety of medical matters and involving various life sciences, such as molecular biology and biophysics; clinical research, which is based on the observation and treatment of patients or volunteers; epidemiological research, which is concerned with the study and control of diseases and of situations that are suspected of being harmful to health; and socioeconomic and behavioural research, which investigates the social, economic, psychological and cultural determinants of health and disease with a view to promoting health and preventing disease. Often a multidisciplinary combination of the above kinds of research is needed to solve a health problem.
